Was the updated version previously dumped?
Nintendo themselves probably just downloaded ROM sets from the Internet. I haven't followed but I heard at least on early Wii VC releases, they were found to include GoodNES ROMs, even including the iNES headers.

All Nintendo home console VC releases use iNES format, modified to patch out stuff. It is only the handheld VC releases (3DS) that use a different format. Notable mention to the NES Classics's headerless PRG+CHR format.

[GG] Sonic Drift Racing (Europe)
[MS] Master Games (Europe)
[MS] Game Box: Série Lutas (Brazil but also released in Portugal)

Sonic Drift Racing probably matches Sonic Drift 2 and the 2 Master System carts are multi game carts that we need to turn the console power on and off to change the game, so maybe the game roms are stored individually...

I get the feeling if anybody had already dumped/figured out how to dump those, it would be the people at SMS Power. They'd dumped the AUS 4-in-1 Pack All Action and CJ Elephant Fugitive for GG, which were supposedly two of the more elusive Sega 8-bit console dumps.
